Continuous vancomycin infusion (CVI) achieved target serum concentrations more effectively than intermittent vancomycin infusion (IVI) for osteomyelitis treatment. CVI also demonstrated fewer adverse drug effects, making it a practical alternative for prolonged high-dose vancomycin therapy.

Area of Science:

  • Pharmacology
  • Infectious Diseases
  • Clinical Therapeutics

Background:

  • Osteomyelitis requires prolonged antibiotic therapy, often with vancomycin.
  • Optimizing vancomycin delivery is crucial for efficacy and safety in high-dose regimens.

Purpose of the Study:

  • To compare the efficacy, ease of use, and safety of intermittent vancomycin infusion (IVI) versus continuous vancomycin infusion (CVI).
  • To evaluate vancomycin pharmacokinetics and clinical outcomes in patients with osteomyelitis.

Main Methods:

  • Prospective study of 44 patients with osteomyelitis receiving vancomycin for over 4 weeks.
  • Patients were divided into IVI (n=21) and CVI (n=23) groups, targeting serum concentrations of 20-25 mg/L.
  • Pharmacokinetics, adverse effects, and clinical efficacy were monitored.

Main Results:

  • CVI achieved target vancomycin serum concentrations more quickly and with less variability than IVI.
  • Adverse drug effects were significantly more frequent in the IVI group (42.9%) compared to the CVI group (8.7%).
  • Intermittent vancomycin infusion and foot osteomyelitis were associated with adverse drug reactions leading to treatment termination.

Conclusions:

  • Continuous vancomycin infusion (CVI) is a practical and effective method for high-dose vancomycin therapy in osteomyelitis.
  • CVI offers a potentially safer alternative to IVI, with fewer adverse events.
  • CVI may be preferred for patients requiring prolonged treatment with high vancomycin serum levels.
